hello , everybody ! I've got a problem on using the VFW . It provides the callback function to deal with the frame captured by the carmera , the callback function has two parameters.
Its Function prototype :

LRESULT CALLBACK FrameCallbackProc(HWND hWnd,LPVIDEOHDR lpVHdr)

but I don't know how to use the second parameter lpVHdr , I want to display the Frame info on a DC , somebody help me , thanks !
